Scientists to develop test for Mad Cow Disease detection

The eyes may or may not be windows to the soul, as the old adage goes, but scientists are reporting evidence that a peek into the eyes of cattle may become the basis for a long sought test to detect infection with the agent that causes Mad Cow Disease. That test could help prevent the disease from spreading in the food supply. A study on using the tell-tale glow given off by eyes infected with the Mad Cow agent appears in ACS' semi-monthly journal Analytical Chemistry.

InfraReDx receives 510(k) clearance to market LipiScan IVUS Coronary Imaging System

InfraReDx, Inc., a medical device company developing intelligent cardiovascular diagnostic imaging technologies, today announced that it has received 510(k) clearance from the United States Food and Drug Administration to market the LipiScan IVUS Coronary Imaging System. LipiScan IVUS is the first cardiac catheter to combine intravascular ultrasound and near-infrared spectroscopy to help cardiologists identify and characterize the plaques that complicate stenting and are associated with acute coronary events.

MRI and MR spectroscopy determine internal fat distribution: Study

Why is it that some people lose weight and body fat when they exercise and eat less and others don't. German researchers say MRI and magnetic resonance (MR) spectroscopy can provide the answer and help predict who will benefit from lifestyle changes.

Scientists discover Magnetic Resonance Spectroscopy can rapidly diagnose degenerative disorders

Magnetic Resonance Spectroscopy can distinguish between neurological diseases in patients without clear symptoms.A team of American scientists claim that a new method of testing for neurological diseases could provide doctors with a rapid and non-invasively method of diagnosing degenerative disorders.

Scientists report global shortage of radioactive isotopes for medical scans

Twenty million medical scans and treatments are done each year that require radioactive isotopes and scientists today described a global shortage of these life-saving materials that could jeopardize patient care and drive-up health care costs.

Magnetic resonance image analysis helps assessment of prostate cancer severity

Rutgers researchers are developing methods that can accurately assess the severity of prostate cancer by analyzing magnetic resonance images and spectra of a patient's prostate gland. This may help physicians decide more confidently which patients need aggressive treatment and which are better served by "watchful waiting," and could even postpone or eliminate invasive biopsies in patients with low-grade tumors.

Scientists develop laser probe for early detection of oral cancer

UC Davis researchers have developed a laser probe for the early detection of oral cancer. A trial with human subjects shows that the device could also be used during surgery to locate the edges of a tumor.

Flow-induced polymer translocation through narrow and patterned channels

An octopus-like polymer can "walk" along the wall of a narrow channel as it is pushed through by a solvent. Now research in The Journal of Chemical Physics, which is published by the American Institute of Physics, provides a theoretical model that compares the transport characteristics of straight- and branched-chain polymers in smooth channels as well as in channels whose walls interact with the polymer -- work that could aid in the development of carrier molecules for delivering drugs at a controlled rate in the body.

Sensory dysfunction affects quality of life of patients with Autism

The way the brain reacts differently to the sense of touch in people with Autism will be examined as part of an innovative Cardiff University study designed to create better understanding of the condition. Dr David McGonigle from Cardiff University's Schools of Psychology and Biosciences will use the latest brain imaging techniques to create a clearer picture of how touch is processed differently.

Volcano second-quarter revenues increase 36% to record $73.5 million

Volcano Corporation, a leading developer and manufacturer of precision intravascular therapy guidance tools designed to enhance the diagnosis and treatment of coronary and peripheral vascular disease, said today that revenues in the second quarter of 2010 increased 36 percent versus revenues in the second quarter of 2009.

Tel Aviv University discovers molecular power behind memory

Neuroscientists have long wondered how individual connections between brain cells remain diverse and "fit" enough for storing new memories. Reported in the prestigious science journal Neuron, a new study led by Dr. Inna Slutsky of the Sackler School of Medicine at Tel Aviv University describes what makes some memories stick.

Research presents theoretical model that predicts HFE values of organic compounds

Drug delivery inside the body is a complicated process. Compounds travel through a maze of aqueous solutions, lipid membranes, and barriers between the blood and tissues like the brain. Research reported in the American Institute of Physics publication the Journal of Chemical Physics presents a theoretical model that accurately predicts the hydration free energy of a wide variety of organic compounds.

Human impact on health of soil, and impact of unhealthy soil on society are intertwined, says LSU researcher

It may sound counterintuitive, but LSU Associate Professor of Chemistry Robert Cook has made a career out of studying the ways organic materials found in the environment, including soils, can either get dirty or stay clean. In fact, the National Science Foundation, or NSF, was so impressed with his efforts that the funding institute awarded Cook one of its most prestigious awards - the NSF CAREER award.

Study may provide physical basis for existence of bubbles that can lead to decompression sickness

As you go about your day-to-day activities, tiny bubbles of nitrogen come and go inside your tissues. This is not a problem unless you happen to experience large changes in ambient pressure, such as those encountered by scuba divers and astronauts. During large, fast pressure drops, these bubbles can grow and lead to decompression sickness, popularly known as "the bends."

Effects of periodic constrictions on drift, diffusion in systems experiencing driving force

An understanding of particle diffusion in the presence of constrictions is essential in fields as diverse as drug delivery, cellular biology, nanotechnology, materials engineering, and spread of pollutants in the soil. When a driving force is applied, displacement of particles occurs as well as diffusion. A paper in the Journal of Chemical Physics, which is published by the American Institute of Physics (AIP), quantifies the effects of periodic constrictions on drift and diffusion in systems experiencing a driving force.
